Abstract
For leak testing closed containers, such containers are placed into a sealingly closed test cavity. From the inside of the container to a space between the outer surface of the container and the wall of the test cavity, a pressure difference is applied which would lead to bowing outwards of flexible wall portions of the container. This is prevented by projections (133) at the wall of the test cavity which supports such wall portions of the container. Recesses (132) between the projections (133) make sure that the installed pressure in the space between outer surface of container and test cavity wall is dissipated all around the container in spite of the projection (133). <IMAGE>
